Description

PROFILED GUIDE RAIL WITH SLIDING OPENING AND LOCKING DEVICE FOR CONTAINERS

FIELD OF THE INVENTION

The present invention relates to a profiled guide rail with slidable opening and closing device for containers, of those which can be used to close spouts in cans and cans which are opened by severing part of the original container lid, to enable partial emptying of the contents with the aid of an internal ventilation of the container.

Exemplary situations for the need for such a closure of openings for the storage of product residues due to partial emptying are above all the gradual product consumption, such as that of condensed and sweetened milk, of carbonated soft drinks in metal or plastic cans in the area of the consumption of food, in addition to viscous ones , effervescent, volatile, caustic or corrosive liquids in the

Product sector for human consumption not necessarily in the food sector, such as pharmaceuticals or cosmetics, but also products for industrial cleaning or for household use, the supply of lubricants for

Motors, as for stationary machines, for the Maintenance of public furniture etc.

The profiled guide rail with a sliding opening and closing device for containers, as an object of the invention, can be used to close pouring openings on cans and cans, and to enable their contents to be partially emptied by pouring, especially cans and cans with a circular base.

BACKGROUND OF THE INVENTION

So far, only such Verschlussvor directions are known that are used with a twist lock or by pressure on a part that comprises the entire diameter of the surface of the opening side of a can or can. As a rule, a circular part of semi-solid plastic material is used, the annular side wall of which is slipped from the outside over the side wall of the can or can, or on a sheet metal lid with a thread. This solution is also used for opening partial opening closures in cans or cans.

Examples of products whose packaging is fully or partially opened on one side as a pouring opening are primarily the aforementioned condensed milk or the soft drinks in aluminum cans, with at least the former having a lid to close it, although not in all of their countries Marketing while in the lids of the offered Aluminum cans with partial opening in the field of soft drinks usually do not reveal any cover that would be added at the factory. To cover and store product residue in these containers, plastic lids must be used, which are usually sold as accessories and not specifically on the can, the opening of which one wishes to close.

In the case of those cans that only have a partial opening on the side of the surface intended for pouring, the undesirable situation of lack of pouring flow can be observed, especially if they are viscous

Liquids such as sweetened milk or oils act by having a inside the container

Negative pressure is created by the property of the slow flow of the liquid, which makes the pouring opening impassable from the inside. In a less pronounced way, this also occurs with non-viscous liquids, whenever the pouring opening is completely covered from the inside. The only possibility of resuming the pouring process is to change the angle of inclination of the container. However, the sudden air inlet into the interior caused by this correction factor usually results in an uncontrolled gush of the pouring spout. It was precisely this problem that led to the spout side being completely covered, as it turned out to be not very practical to add a kind of burin to the cans for multiple perforations of the edges of their surfaces. There is undoubtedly no universal cover for the closure that would offer a solution to the possibility of closing the partial opening to the spout on the can or can lid, which would enable diversified product pouring after opening and which would be an essential part of the same and not just an accessory.

There is therefore a need for a profiled guide rail with a displaceable opening and closing device for containers, for the possibility of closing pouring outlets on them and enabling dosed partial emptying of their contents by pouring out, in particular on cans with lids with a circular base. It is right here where the present

Invention begins.
